We look at the division of 28463473 by 997 
The aim is to understand the frequency of 997 in 28463473.

Going ahead to step 1:
2 divided by 997 is 0 with a remainder of 2.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtracting 0 from 2 leaves us with 2.
Take the next digit (8) from the dividend and append it to 2, then repeat: 28 / 997

Step 2:
997 can be fit into 28 0 times, resulting in a remainder of 28.
Put 0 as the next digit of the answer. 
Result so far: 0.0
If we subtract 0 from 28, we get 28.
Take the next digit (4) from the dividend and append it to 28, then repeat: 284 / 997

On to step 3:
When dividing 284 by 997, we get 0 with a remainder of 284.
Write down 0 as next digit of the result. 
Result so far: 0.0
Deduct 0 from 284 and we're left with 284.
Fetch the next digit (6) from the dividend, attach it to 284 and continue: 2846 / 997

Let's proceed to step 4:
When dividing 2846 by 997, we get 2 with a remainder of 852.
Record the quotient 2 as the next digit in the result. 
Result so far: 2.0
The remainder is 852 after subtracting 1994 from 2846.
Bring next digit (3) of the dividend behind the 852 and repeat the process: 8523 / 997

Let's proceed to step 5:
If we divide 8523 by 997, we get 8 and a remainder of 547.
Use 8 as the next digit of our solution. 
Result so far: 28.0
Subtract 7976 from 8523 to get 547.
Include the next digit (4) from the dividend after 547, then repeat: 5474 / 997

Let's proceed to step 6:
997 goes into 5474 5 times with a remainder of 489.
Put 5 as the next digit of the answer. 
Result so far: 285.0
The remainder is 489 after subtracting 4985 from 5474.
Fetch the next digit (7) from the dividend, attach it to 489 and continue: 4897 / 997

Let's proceed to step 7:
When dividing 4897 by 997, we get 4 with a remainder of 909.
The number 4 becomes the next digit in our result. 
Result so far: 2854.0
If we take 3988 away from 4897, we end up with 909.
Take the next digit (3) from the dividend and append it to 909, then repeat: 9093 / 997

Going ahead to step 8:
When dividing 9093 by 997, we get 9 with a remainder of 120.
The next digit of our result is 9. 
Result so far: 28549.0
The remainder is 120 after subtracting 8973 from 9093.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1200, and continue the process.

Let's proceed to step 9:
When dividing 1200 by 997, we get 1 with a remainder of 203.
Record the quotient 1 as the next digit in the result. 
Result so far: 28549.1
The remainder is 203 after subtracting 997 from 1200.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2030, and continue the process.

Advancing to step 10:
If we divide 2030 by 997, we get 2 and a remainder of 36.
The next digit of our result is 2. 
Result so far: 28549.12
If we subtract 1994 from 2030, we get 36.
Since there are no more digits in the dividend, we add a zero to the remainder making it 360, and continue the process.

Step 11:
997 goes into 360 0 times with a remainder of 360.
Record the quotient 0 as the next digit in the result. 
Result so far: 28549.12
The remainder is 360 after subtracting 0 from 360.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3600, and continue the process.

Advancing to step 12:
The number 997 fits into 3600 3 times, leaving a remainder of 609.
Put 3 as the next digit of the answer. 
Result so far: 28549.1203
The remainder is 609 after subtracting 2991 from 3600.
Since there are no more digits in the dividend, we add a zero to the remainder making it 6090, and continue the process.

On to step 13:
6090 divided by 997 is 6 with a remainder of 108.
Use 6 as the next digit of our solution. 
Result so far: 28549.12036
Subtracting 5982 from 6090 leaves us with 108.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1080, and continue the process.

Let's proceed to step 14:
When dividing 1080 by 997, we get 1 with a remainder of 83.
Use 1 as the next digit of our solution. 
Result so far: 28549.120361
Deduct 997 from 1080 and we're left with 83.
Since there are no more digits in the dividend, we add a zero to the remainder making it 830, and continue the process.

On to step 15:
When dividing 830 by 997, we get 0 with a remainder of 830.
Use 0 as the next digit of our solution. 
Result so far: 28549.120361
Subtract 0 from 830 to get 830.
Since there are no more digits in the dividend, we add a zero to the remainder making it 8300, and continue the process.

Let's proceed to step 16:
When dividing 8300 by 997, we get 8 with a remainder of 324.
Put 8 as the next digit of the answer. 
Result so far: 28549.12036108
The remainder is 324 after subtracting 7976 from 8300.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3240, and continue the process.

The final outcome is 28549.12036108, with a leftover of 3.24e-07.
